Description

Evaporator Vibration System of Vehicle Air Conditioning System {EVAPORATOR VIBRATION DEVICE OF AIR CONDITIONER SYSTEM}

The present invention relates to an evaporator vibration device of a vehicle air conditioning system.

As shown in FIG. 1, a general vehicle air conditioning system includes a compressor (1), a condenser (2), an expansion valve (3), and an evaporator (20) which are sequentially connected to allow a refrigerant to flow through a refrigerant pipe (4). It is configured to have).

In the air conditioning system configured as described above, the air blown by the blower unit is configured to selectively pass through the evaporator or heater installed in the case, and to be supplied to the vehicle interior, which will be described with reference to FIGS. 2 and 3. The description is as follows.

As shown, the upper and lower cases (10, 11) inside the blower fan 15 for blowing the outside air filtered and sucked, and the temperature of the air blown from the blower fan 15 is lowered to the cold air state The main evaporator 20, the heater core 30 for lowering the temperature of the air passing through the evaporator 20 to change to a warm state, and the air passing through the evaporator 20 pass through the heater core 30 ㆍ Temp doors 21 are provided to move to the exit side of the sub-cases 10 and 11 or to the exit sides of the upper and lower cases 10 and 11 without passing through the heater core 30. The outlet side of the upper and lower cases 10 and 11 has branched ducts for supplying air to the floor of the vehicle, the defroster and the vent side, and a plurality of branches for selectively supplying air into the duct at the inlet side of the duct The door 22 is installed The.

In the blowing process of the air conditioning system as described above, the air introduced by the blowing fan 15 and discharged to the room is necessarily discharged to the room via the evaporator 20, the evaporator 20 is a heat exchange for cooling Since the air is maintained at a low temperature in the cooling mode, the condensed water may be generated on the surface of the evaporator 20 due to low saturated steam pressure around it. Therefore, the frequency of occurrence of various bacteria and fungi that can inhabit the evaporator core at high humidity is increasing.

Various techniques have been developed to remove condensate in the evaporator. However, condensate on the surface of the evaporator is still almost removable, and condensate generated in the evaporator cannot be removed. In addition, it was impossible to improve the vehicle's interior environment by creating conditions where bacteria and mold could still be inhabited, and odors were mixed with the blown air and discharged into the room.

The present invention was devised to solve the above problems, to ensure that the condensed water is completely discharged without condensation, to improve the heat dissipation performance, and also to prevent bacteria or fungi, which cause odors, from being inhabited. An object of the present invention is to provide an evaporator vibrator of an air conditioning system capable of providing a vehicle interior environment.

The present invention for achieving the above object, in the vehicle air conditioning system having a compressor, a condenser, an expansion valve and an evaporator which are sequentially connected to the refrigerant flow through the refrigerant pipe, condensed water in one pipe of the evaporator It characterized in that for installing the vibration means to fall in the direction of gravity by vibration.

Hereinafter, with reference to the accompanying drawings a preferred embodiment of the evaporator vibration device of the air conditioning system according to the present invention will be described in detail.

Figure 4 is a side view showing the installation state of the embodiment of the present invention, Figure 5 is a schematic diagram showing the main part of the embodiment of the present invention, Figure 6 is a block diagram showing a control state of the embodiment of the present invention.

The present invention is applied to a vehicle air conditioning system (see FIG. 1) having a compressor, a condenser, an expansion valve, and an evaporator 20 sequentially installed so that refrigerant flows through a refrigerant pipe 4. One side of the pipe (4) 20 is provided with a vibration means 40 to allow the condensed water to fall in the direction of gravity by vibration.

As shown in FIG. 5, the vibrating means 40 includes, for example, a housing 41 formed at one side of the pipe 4, a motor 43 installed inside the housing 41, and the motor. An eccentric body 45 is provided at the end of the shaft 44 of the 43 and rotates together with the shaft 44.

Here, the motor 43 constituting the vibration means 40 is determined to be driven under the control of the microcomputer 50 shown in FIG. 6 to be described later.

Operation according to the present invention configured as described above with reference to Figures 5 and 6 as follows.

First, as shown in FIG. 6, when the ignition switch 51 is turned on and the ignition switch 51 is turned off after a predetermined time after the air conditioner 52 is turned on, the vehicle does not run in the microcomputer 50. You will be judged.

Therefore, the microcomputer 50 outputs a control signal to drive the motor 43 of the vibration means 40.

When the motor 43 is driven under the control of the microcomputer 50, the shaft 44 rotates.

At this time, since there is an eccentric body 45 installed in an eccentric state at the end of the shaft 44, the shaft 44 is rotated to be eccentric with the eccentric body 45.

That is, the eccentric force acts on the shaft 44.

Then, when the eccentric force acts on the shaft 44, the influence is transmitted to the motor 43 and finally to the housing 41 in which the motor 43 is fixed.

Therefore, the vibration is generated in the housing 41, and eventually the vibration of the fine shaking phenomenon occurs in the pipe 4, so that the condensed water falls from the pipe 4 and the evaporator 20.

As described above, according to the present invention, the condensed water is completely discharged without condensation, thereby improving heat dissipation performance, and providing a pleasant indoor environment by preventing bacteria or fungi, which cause odors, from inhabiting. It becomes possible.
